RTX A2000-X3 | a cool&quiet tripple fan mod for the A2000

Wouldn't this mean someone with the right skills could make a custom BIOS with power limit removed, negating the need for a shunt mod?

"The shunt is just a low value resistor. The VRM controller considers this a fixed value, so by knowing the voltage drop across the shunt, it can calculate the current demand.
When you drop the resistance of the shunt, the VRM controller thinks you are pulling less current."

Would the custom BIOS let us directly change the current limit value of the VRM controller?
Or will the VRM controller still check 'electrically / physically' how much current is pulled and react accordingly?

Well, to be completely fair my curve was set to 1590MHz so...

Great results with RTX A2000, congratulations!
Also paying a bit attention to my RTX A2000:
1. Used @REVOCCASES drawings for backplate and memory shim. Thank you very much!
2. Setup custom fan curve with Fan control and received zero prm mode
3. Then followed your guide to OC GPU
But still getting lower results than you, am I doing something wrong? Thank you for help in advance.

Spoiler: temps before and after

Spoiler: 3dmark result + OC setup

P.S.: don't plan to do shunt mod.

My GPU is shuntmodded on front and rear shunt resistor

Sadly no, nVidia still sign the VBIOS, so you can't flash modified VBIOS files

can edit the bios now:

NVIDIA BIOS Signature Lock Broken, vBIOS Modding and Crossflash Enabled by Groundbreaking New Tools

You can now play with NVIDIA GeForce graphics card BIOS like it's 2013! Over the last decade, NVIDIA had effectively killed video BIOS modding by introducing BIOS signature checks. With GeForce 900-series "Maxwell," the company added an on-die security processor on all its GPUs, codenamed...

Hello, i have also modded my RTX A2000 with triple fan mod inspired by @REVOCCASES and @robbee. With slight difference in heatsink and construction. Posting the result and pictures. Now finally quiet A2000 at light PC use and light noise while full load.
Used heatsink and fans:
